Class 12 Mathematics — Relations and Functions Important Questions with Answers (Long answers)
Class 12 Mathematics board is relations-functions, inverse trig, matrices-determinants, calculus (continuity to differential equations), vectors-3D and probability (Bayes, distribution). This hub writes 150+ NCERT-true items. “Integrals class 12 important questions” and “matrices MCQ” are the chips. Twenty questions a page; the key stays closed. No leaked CBSE paper claims.
Reflexive, symmetric, transitive, equivalence, and invertibility of a function. A bijection is the inverse ticket. Composition (fog)(x) needs range-domain fit. Write the proof in the three-line school format when the question says “show that”. You are on Relations and Functions (Long answers), page 1 of 1 — 2 questions in this filter. Long answers model a five-mark write-up: definition, reason, one diagram or equation idea, and a closing line. Do not copy the whole block in the exam; steal the order. This view is for the night before a unit test. Phone layout: chapter chips scroll sideways, answers stay inside a tap, and the next page is a numbered link so Google and students both get a short URL.
